Nevermind Justin Timberlake, Lady GaGa or even Susan Boyle – singer Christina Aguilera's new collaborators are of a distinctly different kind. The legendary riot grrrls of Le Tigre have teamed up with the singer on her new album.

The pop-star/punk-rock team-up was first reported by blogger Perez Hilton. "Just ran into [Le Tigre member] JD Samson, my not-so-secret crush," Hilton wrote on Twitter. "JD tells me Christina is working with Le Tigre on her new album! OMG!" As OMGs continued to rattle across the blogosphere, an official band representative confirmed the news to Pitchfork.

While Aguilera's diverse tastes were already well known – working with everyone from Tony Bennett to Scott Storch to Mark Ronson – Aguilera isn't exactly famous for quoting Bikini Kill lyrics (no matter what critics say). The album's other rumoured contributors, including Goldfrapp, Ladytron and Sia, might be liberated – but they are not nearly so radical as the band who released a song called Dyke March 2001.

The link may be singer-songwriter Sia, who is rumoured to be dating Samson – news that again emerged from the mouth of Perez Hilton. But the stage was set back in 2004, when Le Tigre frontwoman Kathleen Hanna told Entertainment Weekly, "I love Christina Aguilera. She has, like, mini-feminist messages".

Hanna's band have been on hiatus since 2004's This Island, but declared in April, in all-caps, that LE TIGRE HAD NOT BROKEN UP. Their members have instead been teaching classes, having babies and founding new groups with names like, er, Men. And listening, perhaps, to a little bit of Genie In a Bottle.
